Evolution of the indexes
Indexation bases are necessary to provide an automatic re-evaluation of the service contracts.
This function has two main objectives:
- To view the history of the values of an index.
- To enter new values of indexes.
Two re-evaluation methods are available:
- The indexes
- The calculation formulae
Prerequisite
Refer to documentation Implementation
Screen management
Entry screen
To carry out all operation related to an index, it is necessary to select from the list associated with the Index field belonging to the miscellaneous table 410: Indexation basis. Once an index is selected, the history of its values is displayed in the "Value history" grid. The history displays the values classified by the most recent through to the oldest.
To enter a new index value, it is necessary to enter both a date and a value. The entry of these two items of information activates the button . A click on the button recalculates the index value history and purges the contents of the Date and Value fields. A new value can now be entered.
In addition to the comparison of the indexes, it is also possible to establish and to call up calculation formulae entered in the miscellaneous table 427: Re-evaluation formulae.
The execution of these formulae is managed by the entry point called RVACON_ followed by the formula code specified in the contract. For example, the entry point required for the execution of a simple formula would be called RVACON_A1.
The use of re-evaluation by calculation formulae makes up a relevant method for the implementation of contracts with a dynamic calculation basis.
